This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

3 findings rated critical or high. Fix these first.

  1. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing Strict-Transport-Security header

      Forces HTTPS connections

      What to do: Add "Strict-Transport-Security: max-age=31536000; includeSubDomains; preload"

      • CWE-319
      • OWASP A04:2025
      • ASVS V3.4.1
    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  2. SSL/TLS

    TLS encrypts the connection and proves the site is really yours. Weak or expiring certificates trigger browser warnings and put traffic at risk.

    • High

      Weak Protocols Supported

      Server supports weak protocols: TLSv1.1

      What to do: Disable TLS 1.0, TLS 1.1, and all SSL versions

      • CWE-327
      • OWASP A04:2025
      • ASVS V12.1.1

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The company targets the education sector, focusing on students and young people in the Czech Republic. Its business model revolves around issuing discount cards that provide benefits locally and internationally. The presence of partner domains such as shop.isic.cz and cz-online.aliveplatform.com indicates a well-integrated ecosystem for card sales and management. The company leverages trusted third-party services like Google and Meta for advertising and analytics, maintaining GDPR compliance through Cookiebot. The market positioning is stable with a medium-sized operation, and the domain age supports a mature business presence. No direct revenue streams or financial data are disclosed, but the service-oriented model suggests income from card issuance and partnerships.

Security posture

The website maintains a good security posture with HTTPS enabled and use of cookie consent management. No critical security issues or vulnerabilities were identified in the provided content. However, explicit security headers such as X-Frame-Options and X-Content-Type-Options were not found in the HTML snippet and should be verified server-side. There is no evidence of a published security policy or incident response plan on the site. The absence of a security.txt file or vulnerability disclosure page suggests an area for improvement in transparency and security maturity. Overall, the site appears secure for users, with standard best practices implemented.

Recommendations

  1. Add and verify security headers like X-Frame-Options and X-Content-Type-Options to enhance protection against clickjacking and MIME sniffing.
  2. Publish a clear security policy and incident response information to improve transparency and user trust.
  3. Implement a security.txt file to facilitate responsible vulnerability disclosure.
  4. Consider adding explicit contact information for security and general inquiries to improve business credibility.
  5. Regularly audit and update third-party libraries and tracking tools to mitigate emerging vulnerabilities.

Technical notes

Notes

The website uses a modern front-end stack including jQuery, Swiper, Select2, and Leaflet for interactive maps, indicating a rich user experience. Google Tag Manager and Cookiebot are integrated for analytics and privacy compliance. Hosting on AWS provides scalability and reliability. Performance is moderate with deferred loading of scripts, and mobile optimization is good. SEO is supported by proper meta tags and Open Graph data. Accessibility is basic but could be enhanced. No CMS was explicitly detected, suggesting a custom or proprietary solution. Overall, the technical infrastructure supports the business needs effectively with room for modernization in accessibility and security headers.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
